A super acylation catalyst, 4 - dimethylamino pyridine ( dmap ), was prepared and used to synthesize cholesteryl ester compounds. four kinds of cholesteryl ester compounds such as cholesteryl p - alkoxyl benzoate, cholesteryl dicarboxylate, cholesteryl lumequeic ester and coattail - like cholesteryl ester were synthesized by acylation method and super acylation catalyst method. chemical structures and liquid crystal behaviors of the synthesized samples have been characterized by using element analysis, ftir, dsc and polarized microscopy with a hot stage
本文合成了高效酰化催化劑4 -二甲基氨基吡啶（ 4 - dimethylaminopyridine ， dmap ） ，採用酰氯化法和高效酰化催化劑法分別合成了對烷氧基苯甲酸膽甾醇酯、對稱脂族二羧酸膽甾醇酯、烯酸膽甾醇酯及燕尾型膽甾醇酯四類膽甾醇酯衍生物，並進行了化學結構和液晶性能的表徵。There are usually some disadvantages such as more toxicity and low yield in the acetylating reaction which was used to synthesize cholesteryl ester liquid crystals
合成膽甾醇酯常用的酰氯化法存在毒性大，產率低的缺陷。
